I've experienced this once before in my friends XJ when he lifted it. And now it's happening in our Comanche. No lift whatsoever.
My mom DD's it and it happened yesterday and now today too. She describes it as the entire front of the truck shakes and you need to stop to get the shaking to stop.
Last night I tightened every part I had to undo to get the oil pan off. That includes both shocks and sway bar links, the track bar and the UCA's as well as the steering stabilizer and its respective stud. I realize now that it probably wasn't all necessary but you gotta learn somehow. The only thing that I didn't put back on was the stone shield.
After I tightened it all I took it for a five mile test drive that included quick acceleration, aggressive braking and overall road speed. Nothing shook and it drove like it always has.
Everything looks good and I'm out of ideas and I need help.
